Application filed January 29, 1927. Serial No. 1 4,623.

This invention relates to windowfshade rollers and is particularly directed to the mounting at one endof the roller for sup-' porting that end of'the tatably securing a spring carrying spindle within the shade ro-ll.- Theconve'ntional shade roller comprises an outer cloth Winding rear and an inner spindle, said reel rotatably mounted at one end on apivotbracket se- 1 cured to the window frame and at the other on the spindle. The spindle in-turn is non* rotatably secured to a bracket on the w ndow frame and extends well within the, winding reel which serves as a supportfor the roller. The reel is sprmg actuated and its movements are governed by "a mechanism at rotatably securing the spindle to the window the spindle end of the roll, saidmechanismjdescribed in United States Letters Patent N 0.

44,624. The present invention'deals with the 7 construction of the attachment means for nonframe. I

Therefore an object of this'invention is to provide a shank for non-rotatably mounting the spindle, said shank comprising a flat stamping, configurated similarly to an arrow tip, having a narrow f elongated portion socketed into the end of the spindle and its outer end provided with a head, the shoulder thereof preventing longitudinal displacement of a ratchet member which is a part of the reel controllingmechanism, the ratchet member non-rotatably held against the end of the shoulder engagement and the flat end of the spindle serving as the attachment portion adapted to be engaged in a window frame bracket.

Another object is to non-rotatably securing the end of a shade reel spindle, said shank spacing the end of the shade reel away'from the bracket in which the shank is mounted and preventing any injurious contact between the moving reel and the fixed bracket. Y g

Another object is to provide a stamping cut from flat plate adapted to be used as a shank piece for the stationary spindle of a window shade roller, said shank being cheaply manufactured, necessitating less parts and being less apt to break due to its integral structure.

Other objects and certain advantages will be more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which:

Referring to the-drawings, the shadecloth winding reel 1s indicated at 1' and is shown of tubular construction. A spindle 2' is shown mounted within the tubular reel member lat one end thereof for rotatably. supporting that end of the reel; A cap 3 is placed over the end of the shade reel and has its inner end provided with"a"downwardly I turned lip 4 imbedded in the Wood ofthe shade reel. The outer end of the cap provides a flange 5 rigidly maintaining a pawl carrying member 6 against the end of the shade reel. A pair of pawl's 7 are pivotally mounted to the base of the cup-shaped member 6 and are overhung by the flange 5 of the cap. These pawls 7 being'carried by the reel, rotate about, and cooperate with a stationary ratchet member 8 secured at the end of the spindle. The pawl and ratchet mechanism form the means for governing the rotation of the reel on the spindle and are of a well known type. 1

The end of the spindle-2 carries a bearing cap or ferrule 9, the outer end of the ferrule I being formed to provide a shoulder 10 adapted to engage in anaperture centrally of the cup member 6, this being the rota'tive bearing for the reel. Theinner end'of the cap is provided with clip portions 11 for securing the end of the coil spring 12 to the spindle. The spring 12is coiled about the spindle and has its opposite end secured to the reel, being engaged through a plug 13 pinned within the reel. The inner end 14: of the spindle is socketed within the plug in the tubular reel and the opposite end of the shade roller from that described in detail comprises merely a pivot member ima similar bore in the end of the ferrule 9 and is embedded or socketed into the end of the spindle itself, which has been drilled to receive same in a driving-fit. The tip of the' portion 18 may be sharpened for easy insertion and the shank is further maintained against relative movement in the spindle by means of a pin 19. The outer end of the shank provides a head portion 20, and wings or tangs 22 intermediate the shank and head,

the inner shoulder of the wings abutting the face of the stationary ratchet member 8 and holding itagainst the bearing cap or ferrule 9 so as to prevent longitudinal displacement of the ratchet member. The head 20 of the shank is the attachment portion of the shank or mounting for the spindle and is adapted to be rigidly secured in a bracket 21 on the window frame. The outer shoulders of the tangs (see Fig. 1) are disposed slightly beyond the end of the shade roller, so that they engage the bracket 21 and suitably space the roll end away from the bracket thereby preventing scraping of the end of the roll in the stationary bracket.

By this construction the shank serves to hold the ratchet member 8 in place and extends through the end of the bearing cap and also into the spindle, thereby preventing any relative movements of these parts, soas to maintain them all in a stationary position when the head of the shank is secured to the window frame. v

Having described my invention, I claim:

In a window shade roller, a cloth winding reel adapted to be rotatably supported at one end, a spindle mounted in the other end, a spring, one end of which is attached to the reel and the other end to the spindle, adjacent to its outer end, a ferrule disposed over the outer end of the spindle, said ferrule adapted to providea non-rotative anchorage for the spring, pawl mechanism carried by the end of the reel, a cooperating ratchet disposed'against the ferrule upon the outer endof the spindle, and a shank piece, comprising, afiat stamping provided with a tapered end entering the spindle, flanged wings on said stamping bearing against the ratchet to hold the ratchet and the ferrule non-rotatively to the outer end of the spindle and an outer end adapted to bemountedin the roller my name.
